cwoDreCacheStatsDataUnitAge
Module: CISCO-WAN-OPTIMIZATION-MIB
OID (symbolic): CISCO-WAN-OPTIMIZATION-MIB::cwoDreCacheStatsDataUnitAge
OID (numeric): 1.3.6.1.4.1.9.9.762.1.7.1.7
Node type: OBJECT-TYPE
Type: SnmpAdminString
Access: read-only
Description: This object indicates the age of oldest data unit in the data
block. DRE stores the actual data as data units in the data
block and the metadata (chuck signature) in signature block. If
new data unit should be written to the data block when it is
full, then the oldest data unit currently present in the data
block will be evicted. So this object would indicate the age
of the oldest data unit present in the DRE cache. It takes the
format of
What is cwoDreCacheStatsDataUnitAge?
This read-only SnmpAdminString indicates the age of the oldest data unit in the data block, formatted as <x>d<x>h<x>m per the description, reported specifically for the data-unit portion of the cache as opposed to the signature block. An admin uses this to judge how long data unit content survives in cache before being evicted, complementing the overall cwoDreCacheStatsAge with a data-unit-specific view. A very short age here relative to expectations would signal rapid data-unit turnover, suggesting the cache is undersized for the current traffic's uniqueness.
